Abstract

The present invention relates to a current divider for a measuring transducer. The current divider includes two conductors. The first conductor, which is operable as a shunt, comprises two generally flat legs which extend parallel to one another. Each leg defines one aperture into which the core of the measuring transducer extends. The second conductor is z-shaped having two arms and a bridge extending between the two arms. The arms are electrically connected to one of the legs and the bridge crosses the aperture therein, so that the bridge is surrounded by the core.
